69be02c0fd Set the default auxiliary sends to MAX_SENDS 
Since the property is ALC_MAX_AUXILIARY_SENDS, it makes more sense to default
it to the maximum and let the app lower it on request.

eefda551de Properly handle input samples for changes with the FIR coefficients 
This makes sure previously processed samples are not changed due to changes in
the FIR filter. It also applies the coefficients in ascending order with the
values, to improve caching.

5736bbc3e4 Add a source property to skip channel virtualization for multi-channel buffers 
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.

The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.
